GAS R'EGULATOR AND CUT OFF.

SPECIFICATION f rming part of Letters Patent No. 362,973, dated LTay 1'7, 188?.

Application filed February 17, 1887. Serial X0. 227,922. (No model.)

To aZZ whom it may concern.-

Be it known that l, Trno'rny J. :IEl'.'EY, of

the city, county, and State of New York, have invented a new and useful Improvement in GasRegulators and Cut-Ol'fs,ot which the following is a full, true, and complete description, reference beinghad to the accompanying drawings.

This invention relates to ii'nprovcments in apparatus by which the pressnresupply to a building may be regulated and at times cut oil.

My invention will be readily understood from the accompanying drawings, in which similar letters refer to similar parts.

Figure 1 is a cross'section of the entire apparatus. Fig. 2 is a crosssection at right angles to Fig. 1. Fig. 3 is a view of a.modification.

The diaphragm A is inclosed in a suitable chamber. Connected in the bottom of this diaphragm is the link B, which operates the rock-shalt G. This rock-shaft is provided with a ground-disk, D,\vhich makes a substantially tight joint against the side of the chamber E. Two arms, F and G, connected with the rock-shaft operate valves II and J, as shown. The spring K tends to hold the disk D against the side of the chest. It will be ob served that the valves J and II open and close alternately. Gas enters the apparatus at L and escapes at M. The diaphragm is held down by suitable weights, N, for which a spring could be substituted. Under the ordinary conditions of operation the valveH, be tween the chambers E and L, is open. passes said valve II and valve J into the chamber \V, beneath the diaphragm. XVhen this pressure is sutiicient to raise the weights, the regulating-valve J tends to close. In case of an entire cessation in the gaspressurc, the diaphragm falls, thereby closing the valve H, as shown in Fig. 2. In order to again admit gas to the apparatus,the dome V must be unscrewed and the diaphragm raised, when the valve H will again open.

In Fig. 3 I have shown a modification in Gas which the disk D is formed into a valve and is substituted for J. Under these cireunr stances the disk is provided with one or more openings, as shown,corresponding to openings Sin the chest. These openings areso arranged as that when the diaphragm A is raised the ports will be closed. The operation is the same as before.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a gas-regulator, of a suitably-snpported diaphragm, A, link B, rock-shaft C, and valves H and J, operated by arms projecting laterally from said rock-shaft,

arms projecting laterally from said rock-shaft,

said rock-shalt being provided with grounddisk D and closing spring K, substantially as described 3. The combination, in a gas-regulator, of

a suitablysnpported diaphragm, A, link B,

rockshai't 0, provided with rotating disk I), having openings therein, in combination with the ports S in the valve-chest, substantially as described.

4. In a gas-regulator, a casing incloslng a chamber, L, in communication with the main supply-pipe, a chamber, \V, in communication with the delivery-pipe, and a chamber, E, in

communication with said chambers L and \V, in combination with a diaphragm in said cham- 5c beriV, valves closingcommunication between said chambers E, L, and \V, and a rock-shaft controlling said valves and controlled by said diaphragm, substantially as described.

In testimony whereofI have signed my name 8 to this specification in the presence oftwo subscribing witnesses.
